Whether after we format the phone using MFI which files, commands, codes, etc, still on it?.I'm making this question because I saw many times that doing this format the brand's VSM (being, T-Mobile, at&t, verizon or whatever) still there and also because many buttons on the MFI screen showing that there is a lot information stilling on the phone. And being in that way how we can get this information?.I think that knowing it there could be many things that it can help to fix a software issue

Not sure I understand what your asking but if you are saying the BB is still marked or locked to the original carrier after a wipe then you are correct . You cannot remove the carriers tag unless you follow the process to replace the OS with a OS that is untagged. If you are talking about using the BB on a different carrier then you need to use a vendor that offers an unlock code. A vendor sponsor in the Forum is Horizon. Do a search for further information on unlocking etc.

I was a bit suspicious but just in case I misunderstood the OP I gave it a shot at something legitimate. I could not find any reference to that MFI stuff.

Thanks

Ok. Sorry about MFI I didn't know that it was an illegaly stuff because you can find it in many place on the internet, but anyway the point is: I have an unlocked phone then I removed the OS getting just a blank creen saying something like "no OS device" and I want to know being the phone in this situation are in the phone comands, files, codes or whatever stuff yet?, or is it completely erase?.I don`t think so because the phone has ROM (where it should be a DOS such as the PCs) and it should be still intact after a format, right?. I need to know that because I have a phone (8310) with a conflict with de BBM (and it is no way.It has two days working perfectly without it) and I'm sure that I can't fix this issue just formating it because the ROM of the phone is which has a a command damage or something that it is causing this conflict with the BBM and throw the phone because that issue it couldn“t have any sense. In other words there should be a way to FLASH the BB EPROM like we can do it with the PCs.Sorry with my English

Yes, nothing you find on the internet waranty that it is legal but in fact the point is that it is on the internet and everyone can access to it if he knows how. And about if my phone is damage, brik, broken or whatever like that, I never wrote that I wrote that it has a very weird issue seeming that it exists a conflict with the BBM. It is working perflectly now for almost three days but I don't have the BBM on it. Do you understand?.And I know that it is not a PC,Android,Iphone or something like them and besides I said that "it should..." and it is a conditional not an imperative like "it must....". Maybe my English is very poor but I think that if someone takes a little time to read what are my concerns in my other prompts somebody could understand what Ķ need to solve and perhaps it can help to somebody else.Thanks for your help !!

You 8310 is working without Blackberry Messenger and you don't know why?
Blackberry messenger isn't required to make a blackberry work perfectly. Its an extra application.
Are you wanting to USE blackberry messenger and can't?

No, I know that.And yes the problem is that when I installed BBM the phone won't work and after a while It will get reset and the error 523 on a blank screen.Thanks !!

Is the BBM version compatible with the OS version installed on your BB?

I have now the 4.5.180 (320) and before the 4.5.0.9x I don't remember but anyway the phone has the same behavior with both.Another thing I discovered today is that in Applications the BBM still in there but the icon in the home-screen disappear.Thanks !!

Well I don't know what happened but the truth is that tonight I installed again BBM 5.0 and seems that the phone is working now doing anything more.What did I before?, I really don't know I did many things.Among them I worked with the e-screen and I displayed the event log searching conflicts or errors. And I killed one process and I disable one permission in who knows which module. But the point is that seems that it is working now. Anyway I hope that I won't get this problem again.Thanks for your attention !!!
